Huo Xing Finance reports that, according to official announcements, Coinbase’s Layer 2 network Base will soon launch the Beryl hard fork upgrade, introducing the B20 native token standard, reducing the single-proof withdrawal finality period from 7 days to 5 days, and upgrading to Reth V2 (reducing disk usage by 50% and increasing throughput by 33%). Beryl will be activated on the Sepolia testnet at 2:00 AM (UTC+8) on June 19 and on mainnet at 2:00 AM (UTC+8) on June 26. B20 is Base’s native token standard—a Rust-based precompiled ERC-20 compatible token designed specifically for stablecoins, RWA, and long-tail token issuers, featuring an integrated compliance toolkit including transfer policies, freezing and seizure capabilities, role-based access control, memos, and supply caps. Regarding withdrawals, the final adjudication window for the single-proof dispute resolution process is reduced from 7 days to 5 days. The dual-proof fast lane (TEE+ZK) introduced by Azul remains at 1 day.
